In a photomultiplier tube, assume that there are seven diodes with potentials 100, 200, 300, 400, 500, 600, and 700 V. The average energy required to free an electron from the dynode surface is 10 eV. For each incident ectron released from rest, how many electrons are freed at the first dynode? At the last dynode?
